Got a 06 GTO, planning on adding a D1SC.
What y'all think?

8 lbs to start
meth inj with IAT breakout
93 pump gas
OEM heads with .650 springs, ARP studs, OEM gaskets
FAST 102
Siemens 60 lb injectors
LPE fuel pump
Kenne Bell boost-a-pump
Torquer v2 232/234 595/598 111 LSA
Kooks Signature Series long tubes
Stock bottom end
Monster stage 1 twin disc
Tuned by Vengence.

I know it's not an ideal cam for a blower, but I like the duration for drivability below 2,000 rpm... and the way the 11 degrees of overlap sounds at idle. Ridin with a 236/238 113 LSA now and the bucking and jiggling below 2,000 is about to drive me insane (unchanged by VE and MAF tuning). The Torquer v3 231/234 111 LSA that I used to have was perfect above 1400 rpm.



Comments?
whp guesses?

You would be better off keeping the 113lsa cam, once you have the blower on you'll want to keep it above 2k anyway.

the fast 102 probably isnt needed , what you will spend on that setup you could do meth and be better off . stick with the ls6 intake and do meth .

Exactly. I would not even waste the money on the fast 102. Stock Ls6 Intake on my Ls1 and is making over 800 to the tire.

Thanks for the replies everyone.

Yeah it'll be above 2 grand a bit, but this is my daily driver. Therefore it sees a lot of 40mph 5th gear 1500rpm driving. The drivability of the 236/238 113 just plain sucks below 2000 rpm. Its about to drive me crazy. Granted I'll prolly be on a SD tune with the blower which will buck less, so, I don't know.

And as far as the FAST 102 goes, it's been bolted on the car since the last build.

I'm not on the fence with the meth inj due to cost... I'm fine with that part. I'm just iffy about the hassle of refilling and danger to the motor if it runs out/fails. I know you can inject it after a broke-out IAT and pull timing when IAT temps go up when the meth stops, but this is all new to me and I'm unsure about exactly where to put everything (more searching needed on my part).

Thanks again for the input everyone. I really appreciate it! I know I don't have many posts, but I've been Googling this site for well over a year. Everything I know about LS motors I pretty much learned from you guys on here.

find out if the voltage booster on your stock fuel pump is going to cut it. don't fool around with lean conditions ever

I'd go with 8 psi, these engines do very well at 8 psi with a good tune.
With the Lingenfelter fuel pump you won't need to use a boost a pump. You can, but you won't need it.
The FAST 102 is waay better than the LS2 intake. The LS2 intake is inferior to the LS6 intake, so since you already have the FAST you're better off.
Have you checked out my blower cam? There are plenty of sound clips with it, and with a good tune it is very streetable. http://shop.brutespeed.com/Brute-Spe...d-Camshaft.htm Bob

Thanks for the info, Bob.

I think I'm gonna go with the meth kit because with it being 80 degrees today my IATs were 110-120 even with easy driving. Also 8 lbs should be easy with meth, I imagine.

As far as the cam goes, I think I'm gonna do the Torquer v2 111LSA this time around. I like low 230s duration and about 10 or 11 degrees of overlap. I think it will give me more power around 2500 and will make for reversion-free 1500 rpm cruising. It will hurt my top end for sure but I'll let the procharger make up for that. I've had a 228r, Torquer v3, and VRX5. The Tv3 was my favorite for low end power and drivability... But I'm not a fan of its 643 lift, hence the low lift of the Tv2 I've chosen.

I've seen a car identical to mine make 520 rwp with a Tv2, minus the meth, but it was an auto. Can I get a 575 with meth? Ye-ah (maybe)

Rwhp guesses for 8lbs with 60 lb inj, LPE fuel pump with a BAP, FAST 102 (already bolted on), Torquer v2 232/234 595/598 111LSA, Kooks long tubes?

Bob@BruteSpeed

You're welcome. I'd say 550 to 600 rwhp. Bob

Bob I'm liking your input more and more. Haha

I have HPtuners and the car will be tuned with EFIlive this time.
If my tuner uses EFI Live and changes the operating system to SD/2 bar (at least that's what it offers in HPtuners), then will I be able to tune everything normally myself (as if I changed it over to that OS using HPtuners)?

AbsolvedJD

Bump.

I am not a tuner so I can't answer that. One thing I can tell you though is that unless you have experience tuning for forced induction, it is best to leave it to someone who is. Bob

Thanks for the tip Bob. I'm definitely not doing the initial tune. Haha. Scary stuff there. But I will be slightly tweaking things like startup airflow and whatnot.

Anyone else familiar with OS cross compatibility between EFIlive and HPtuners after an OS upgrade to 2 bar/SD using EFIlive?


Addendum: There's no harm in installing the black ATI bypass valve on just 8-10lbs, is there? Reason is, I cruise on the interstate on the way to work at 2K for about 13 miles each way, 3x a week. I think it's justified.

thehazz12

I wouldn't think there would really have to be much compatibility with what you're wanting to do, but I don't know a whole lot about either program. Haven't really been able to use my HPT that much yet. I've only done a few logs so far...

My thought process: If the original tune is done with EFI Live, I would think you would still be able to download the tune from the car onto your HPT and then make your own changes.

I agree.

Now, anyone have any thoughts about the bypass valve:

The black Proflow bypass valve is good to 14 psi or so. Bob

Also, how much rwhp is my fuel setup gonna be good for(LPE fuel pump, Siemens 60 lb injectors, boost-a-pump)?

~650 at the wheels?

AbsolvedJD

iTrader: (12)

May add TFS 225s with 68-71cc chambers. Would love to get around 625 guaranteed whp out if this. As long as my fuel setup will support 650 at the wheels.

Ordering SCSS dash gauge pod and gauges. Look good but man they're pricey.

Any thoughts on how much rwhp a Lingenfelter fuel pump with a boost-a-pump and 60 lb injectors can handle?
